RJ IS NOT ROBERT KIRKLAND. And you can safely say he isn't a friend of RJ either. Go to the mentalist season 5 on wikipedia; en.wikipedia.org/wiki/The_Mentalist_%28season_5%29 and look at the episode 19 information it says; "While the CBI investigates a murder at a Wild West theme park, an
inquisitive Kirkland presses Jane for information about Red John." Why would he ask about info on RJ if he's supposedly RJ's accomplice? The reason he is asking Jane for information is because he too is also trying to capture RJ.
